Slimhole EM integrity

Pulse1

Tube integrity diagnostics delivering true wall thickness

Pulse1 is the newest addition to our Pulse electromagnetic platform; one of five proprietary platforms that provide powerful through-barrier diagnostics to the oilfield.

Pulse1 is the industry’s first slimhole tube integrity technology capable of delivering ‘true wall thickness’ measurements of production tubing in eight sectors, with complete "all-around" sensing of tube wall condition.

Pulse1 has been designed to meet the growing industry need for "no compromise" integrity management, and overcome the drawbacks of current technologies, especially multifinger calipers and conventional electromagnetics.

Calipers measure internal diameter and estimate wall thickness by assuming a ‘nominal’ outside diameter (OD).

Applications

Variations in the actual OD and external corrosion, both invisible to calipers, can invalidate the thickness value. Similarly, scale or wax deposits on the inner surface can mask internal defects and lead to further false readings. Pulse1’s ability to measure actual wall thickness in multiple sectors eliminates these issues, delivering greater accuracy in a wider range of scenarios.

Another consideration with calipers is coverage. Caliper fingers touch 10-30% of the inner wall surface, so localised metal loss can be missed. And in corrosion resistant tubulars, the millimeter-thin fingertips could scratch protective coatings, exposing the alloy beneath.

Pulse1 overcomes these challenges and many more, making it the ideal choice for routine or targeted tube integrity surveillance.
